I grabbed this code from a version of Win32Lib that does work:

global function getTVIndex( atom id )
    atom count, state, item, lParam, TV_ITEM

    TV_ITEM = struct_TVITEM( 0, 0,
	        0, TVIS_SELECTED, "", 0, 0, 0, 0)

    count = sendMessage( id, TVM_GETCOUNT, 0, 0 )

    lParam = 0
    item = sendMessage( id, TVM_GETNEXTITEM, 0, TVGN_ROOT )
    w32store( TV_ITEM, TVITEM_hItem, item )
    VOID = sendMessage( id, TVM_GETITEM, 0, TV_ITEM )
    for i = 1 to count do
        state = w32fetch( TV_ITEM, TVITEM_state )

        if and_bits(state, TVIS_SELECTED) then
            lParam = w32fetch( TV_ITEM, TVITEM_lParam)
            exit
        end if

        item = sendMessage( id, TVM_GETNEXTITEM, TVGN_NEXTVISIBLE, item )
        w32store( TV_ITEM, TVITEM_hItem, item )
        VOID = sendMessage( id, TVM_GETITEM, 0, TV_ITEM )
    end for

    w32release_mem( TV_ITEM )

    return lParam

end function

global function getTVText( integer iItem )
    if iItem > 0 and iItem <= length(tvitem_data) then
        return w32peek_string( tvitem_data[iItem][ktv_TextAddr] )
    else
        return ""
    end if

end function
